Abstract

The embodiment of the invention provides a data stream merging method and a device, electronic equipment and a computer storage medium. The method comprises the steps that receiving multiple data streams sent from an flink data source, wherein the data structures of at least two data streams in the plurality of data streams are different; acquiring a configuration file used for merging the plurality of data streams; filtering the plurality of data streams according to the configuration file to obtain filtered data streams; and for the filtered data stream, acquiring the data stream stored in a Map data structure within a set waiting time, and based on the configuration file, carrying out merging processing on the data stream stored in the Map data structure within the set waiting time.

Description

technical field [0001] The present application relates to the field of big data real-time computing of financial technology (Fintech), and in particular to a data stream merging method, device, electronic equipment and computer storage medium. Background technique [0002] With the development of computer technology, more and more technologies are applied in the financial field, and the traditional financial industry is gradually transforming into financial technology. However, due to the security and real-time requirements of the financial industry, higher requirements are also placed on technology. [0003] In related technologies, there are mainly two types of multi-stream merging schemes: 1) multi-real-time stream merging scheme based on flink union; 2) multi-real-time stream merging scheme based on flink connect; scheme 1) union algorithm provided by flink The child performs multi-real-time stream merging processing, see Figure 1A , taking two real-time streams as an e...
